Description

附黏著劑層之偏光薄膜Polarizing film with adhesive layer

發明領域 本發明涉及一種具有於液晶單元內部納入觸控感測機能之內置型液晶單元及於該內置型液晶單元之視辨側具有附黏著劑層之偏光薄膜的內置型液晶面板。此外，本發明涉及一種使用該液晶面板之液晶顯示裝置。使用本發明之內置型液晶面板的附觸控感測機能之液晶顯示裝置可作為行動機器等各種輸入顯示裝置使用。 Field of Invention The present invention relates to a built-in liquid crystal cell with a touch-sensing function incorporated in the liquid crystal cell, and a built-in liquid crystal panel with a polarizing film with an adhesive layer on the viewing side of the built-in liquid crystal cell. Furthermore, the present invention relates to a liquid crystal display device using the liquid crystal panel. The liquid crystal display device with a touch sensing function using the built-in liquid crystal panel of the present invention can be used as various input display devices such as mobile devices.

發明背景 液晶顯示裝置一般是從其影像形成方式，於液晶單元兩側隔著黏著劑層而貼合有偏光薄膜。另外，於液晶顯示裝置之顯示畫面搭載觸控面板之產品業已實用化。就觸控面板而言，有電容式、阻抗膜式、光學式、超音波式或電磁感應式等各種格式，近期多採用電容式。近年多使用內嵌有電容感測器作為觸控感測器部之附觸控感測機能之液晶顯示裝置。 Background of the Invention In liquid crystal display devices, generally, polarizing films are attached to both sides of the liquid crystal cell via an adhesive layer from its image forming method. In addition, products incorporating a touch panel on a display screen of a liquid crystal display device have been put into practical use. As far as touch panels are concerned, there are various formats such as capacitive type, resistive film type, optical type, ultrasonic type or electromagnetic induction type. Recently, capacitive type is mostly used. In recent years, a liquid crystal display device with a touch-sensing function embedded with a capacitive sensor has been widely used as the touch-sensing part.

就製造液晶顯示裝置方面來看，將前述附黏著劑層之偏光薄膜黏貼至液晶單元時，會從附黏著劑層之偏光薄膜之黏著劑層剝離脫模薄膜，而因該脫模薄膜之剝離產生靜電。又，在剝離貼附於液晶單元之偏光薄膜的表面保護薄膜時或在剝離覆蓋窗的表面保護薄膜時也會產生靜電。因而產生的靜電會影響液晶顯示裝置內部的液晶層配向，招致不良後果。所以，例如藉由在偏光薄膜外面形成抗靜電層，可抑制靜電的產生。In terms of manufacturing a liquid crystal display device, when the aforementioned polarizing film with an adhesive layer is pasted to a liquid crystal cell, the release film is peeled off from the adhesive layer of the polarizing film with an adhesive layer. Static electricity is generated. In addition, static electricity is also generated when peeling off the surface protective film of the polarizing film attached to the liquid crystal cell or when peeling off the surface protective film of the cover window. The resulting static electricity may affect the alignment of the liquid crystal layer inside the liquid crystal display device, resulting in adverse consequences. Therefore, for example, by forming an antistatic layer on the outside of the polarizing film, the generation of static electricity can be suppressed.

另一方面，附觸控感測機能之液晶顯示裝置的電容感測器係用以檢測使用者手指接近其表面時透明電極圖案與手指所形成之微弱的電容量。如果於上述透明電極圖案與使用者手指之間具有如抗靜電層之導電層，驅動電極與感測器電極間之電場會紊亂，造成感測器電極容量不穩定，降低觸控面板敏感度而成為故障之原因。就附觸控感測機能之液晶顯示裝置來說，必須抑制產生靜電以及電容感測器之故障。例如針對前述課題，有文獻提議在附觸控感測機能之液晶顯示裝置中於液晶層之視辨側配置偏光薄膜以減低顯示不良或故障的發生，該偏光薄膜具有表面電阻值為1.0×10 9~1.0×10 11Ω/□之抗靜電層(專利文獻1)。 先前技術文獻 專利文獻 On the other hand, the capacitive sensor of the liquid crystal display device with touch sensing function is used to detect the weak capacitance formed by the transparent electrode pattern and the finger when the user's finger approaches the surface. If there is a conductive layer such as an antistatic layer between the above-mentioned transparent electrode pattern and the user's finger, the electric field between the driving electrode and the sensor electrode will be disturbed, resulting in unstable sensor electrode capacitance, reducing the sensitivity of the touch panel. be the cause of the failure. For a liquid crystal display device with a touch sensing function, it is necessary to suppress the generation of static electricity and the failure of the capacitive sensor. For example, in view of the aforementioned problems, some literatures propose to arrange a polarizing film on the viewing side of the liquid crystal layer in a liquid crystal display device with touch sensing function to reduce the occurrence of poor display or failure. The polarizing film has a surface resistance value of 1.0×10 Antistatic layer of 9 to 1.0×10 11 Ω/□ (Patent Document 1). Prior Art Documents Patent Documents

發明概要 發明欲解決之課題 藉由專利文獻1中記載之具有抗靜電層的偏光薄膜，可某程度抑制靜電產生。但，在專利文獻1，抗靜電層之配置場所離產生靜電的根本位置較遠，所以效果比不上對黏著劑層賦予抗靜電機能。另已知在使用內置型液晶單元之附觸控感測機能之液晶顯示裝置中，藉由於偏光薄膜側面設置導通結構，可賦予來自側面的導通性，不過當抗靜電層很薄時，側面與導通結構的接觸面積小，便無法獲得充分的導電性而發生導通不良。另一方面，抗靜電層一旦變厚，觸控感測器敏感度就會下降。 Summary of Invention The problem to be solved by the invention With the polarizing film having an antistatic layer described in Patent Document 1, the generation of static electricity can be suppressed to some extent. However, in Patent Document 1, since the place where the antistatic layer is arranged is far from the fundamental position where static electricity is generated, the effect is not comparable to that of imparting an antistatic function to the adhesive layer. It is also known that in a liquid crystal display device with a built-in liquid crystal cell with a touch sensing function, the conduction structure can be provided on the side of the polarizing film to provide conduction from the side. However, when the antistatic layer is very thin, the side and When the contact area of the conduction structure is small, sufficient conductivity cannot be obtained and conduction failure occurs. On the other hand, once the antistatic layer becomes thicker, the sensitivity of the touch sensor decreases.

此外，被賦予抗靜電機能的黏著劑層比設置於前述偏光薄膜上之抗靜電層更能抑制靜電產生，可有效防止靜電不均。但也清楚一旦因為重視黏著劑層之抗靜電機能而提高黏著劑層之導電機能，會降低觸控感測器敏感度。特別是在使用內置型液晶單元之附觸控感測機能之液晶顯示裝置中，觸控感測器敏感度會下降。此外已知，為提高導電機能而摻混於黏著劑層中之抗靜電劑在加濕環境下(加濕可靠性試驗後)會偏析於與偏光薄膜之界面或移動到液晶單元之視辨側界面，耐久性不足。In addition, the adhesive layer endowed with antistatic function can suppress the generation of static electricity more than the antistatic layer provided on the polarizing film, and can effectively prevent unevenness of static electricity. However, it is also clear that once the conductive function of the adhesive layer is improved due to the antistatic function of the adhesive layer, the sensitivity of the touch sensor will be reduced. In particular, in a liquid crystal display device with a built-in liquid crystal cell with a touch sensing function, the sensitivity of the touch sensor is reduced. In addition, it is known that the antistatic agent blended in the adhesive layer for the purpose of improving the conductive function will segregate at the interface with the polarizing film or move to the viewing side of the liquid crystal cell in a humidified environment (after the humidification reliability test). interface, lack of durability.

As the conductive polymer, those soluble in organic solvents, water-soluble and water-dispersible can be appropriately used, but water-soluble conductive polymers or water-dispersible conductive polymers are preferably used. Since the water-soluble conductive polymer or the water-dispersible conductive polymer can prepare the coating liquid for forming the antistatic layer into an aqueous solution or a water dispersion liquid, the coating liquid does not need to use a non-aqueous organic solvent, and can suppress the optical film base. The material is due to the deterioration of the organic solvent. In addition, the aqueous solution or the aqueous dispersion may contain an aqueous solvent other than water. For example, methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, secondary butanol, tertiary butanol, n-amyl alcohol, isoamyl alcohol, secondary amyl alcohol, and tertiary amyl alcohol can be mentioned.

(甲基)丙烯酸系聚合物在總構成單體之重量比率中係以(甲基)丙烯酸烷基酯作為主成分，且(甲基)丙烯酸系聚合物中之前述共聚單體的比例無特別限制，前述共聚單體的比例在總構成單體之重量比率中佔0~20%左右，以0.1~15%左右為宜，0.1~10%左右更佳。The (meth)acrylic polymer has an alkyl (meth)acrylate as the main component in the weight ratio of the total constituent monomers, and the ratio of the aforementioned comonomer in the (meth)acrylic polymer is not particularly Restriction, the proportion of the aforementioned comonomers accounts for about 0~20% in the weight ratio of the total constituent monomers, preferably about 0.1~15%, more preferably about 0.1~10%.

從黏著性、耐久性的觀點來看，該等共聚單體中又宜使用含羥基單體、含羧基單體。含羥基單體及含羧基單體可以併用。當黏著劑組成物含有交聯劑時，該等共聚單體會成為與交聯劑反應的反應點。含羥基單體、含羧基單體等在分子間與交聯劑富有反應性，所以很適合用來提升所得黏著劑層之凝聚性及耐熱性。在重工性之觀點上以含羥基單體為宜，又在兼具耐久性及重工性的觀點上則以含羧基單體為宜。From the viewpoint of adhesiveness and durability, among these comonomers, hydroxyl group-containing monomers and carboxyl group-containing monomers are preferably used. The hydroxyl group-containing monomer and the carboxyl group-containing monomer may be used in combination. When the adhesive composition contains a cross-linking agent, these comonomers become reactive sites for reaction with the cross-linking agent. Hydroxyl-containing monomers, carboxyl-containing monomers, etc. are intermolecularly reactive with cross-linking agents, so they are very suitable for improving the cohesion and heat resistance of the obtained adhesive layer. From the viewpoint of reproducibility, the hydroxyl group-containing monomer is suitable, and from the viewpoint of both durability and reproducibility, the carboxyl group-containing monomer is suitable.

共聚單體含有含羥基單體時，其比例宜為0.01~15重量%，0.03~10重量%較佳，0.05~7重量%更佳。共聚單體含有含羧基單體時，其比例宜為0.05~10重量%，0.1~8重量%較佳，0.2~6重量%更佳。When the comonomer contains a hydroxyl group-containing monomer, its proportion is preferably 0.01 to 15% by weight, preferably 0.03 to 10% by weight, and more preferably 0.05 to 7% by weight. When the comonomer contains a carboxyl group-containing monomer, its proportion is preferably 0.05 to 10% by weight, preferably 0.1 to 8% by weight, and more preferably 0.2 to 6% by weight.

本發明之(甲基)丙烯酸系聚合物通常係使用重量平均分子量在50萬~300萬範圍之物。若考慮耐久性尤其是耐熱性，宜使用重量平均分子量為70萬~270萬之物。更以80萬~250萬為宜。重量平均分子量若小於50萬，在耐熱性觀點來看不宜。又，重量平均分子量若大於300萬，為了調整用以塗敷之黏度，需要大量的稀釋溶劑而增加成本，故不適宜。另，重量平均分子量係指以GPC(凝膠滲透層析術)測定且經聚苯乙烯換算計算所得之值。The (meth)acrylic polymer of the present invention is generally used with a weight average molecular weight in the range of 500,000 to 3,000,000. In consideration of durability, especially heat resistance, a weight-average molecular weight of 700,000 to 2,700,000 is preferably used. It is more appropriate to use 800,000 to 2.5 million. If the weight average molecular weight is less than 500,000, it is unfavorable from the viewpoint of heat resistance. Moreover, if the weight average molecular weight exceeds 3 million, in order to adjust the viscosity for application|coating, a large amount of diluent solvent is required and cost increases, and it is unfavorable. In addition, the weight average molecular weight means the value calculated by GPC (Gel Permeation Chromatography) and calculated in terms of polystyrene.
